Non-Invasive Vascular Labs

The ABI Physiologic Tests (such as Pulse Volume Recordings or PVRs) will provide diagnostic information to the physician so he/she can determine the amount of circulation to the extremities. There are actually two parts that make up the PVR test: Ankle Brachial Index (ABI) and plethysmographic waveform analysis. ABI’s - a comparison between the ankle systolic blood pressure and the brachial systolic blood pressure - are easy to perform and can provide valuable information. Most often used to identify peripheral vascular disease, abnormal ABI’s can also be a marker for unsuspected coronary artery disease. The usefulness of the ABI reading is often limited in patients with calcified arteries, diabetes and patients with advanced renal disease. The addition of PVR’s – with the production of wave forms using plethysmographic techniques-increases the utility and accuracy of the ABIs when examining the extremities for arterial insufficiency. Careful examination and analysis of the waveforms at various levels will allow the physician to localize blockages and occlusive diseases specific to various segments of the arterial tree.
The utilization of noninvasive vascular testing will yield answers to specific questions and is a valuable management tool for physicians in their office practice, clinics, diagnostic centers and hospitals. Utilization of these tests will allow patients to have the peace of mind that comes with accurately knowing the health of their vascular system.
